Hello all, I have a problem with the header tank to the central heating overflowing. I've checked on this forum & followed all the advice but it seems the heating coil inside the indirect hot water cylinder is leaking. The system has been filled from new with Fernox, & I replaced the fernox 3 years ago.
Now, would it be possible to use a "leak sealer" to solve the problem, & if so, how do I get it into the hot water system?
many thanks
